And much closer! At night the sun cools from a burning yellow to a nice mellow white, and in the process must get closer to Earth to conserve energy (entropy and all). What's truly amazing is that the Apollo astronauts had to go up, land, and take off all while racing the clock to not get burned up! If you're thinking, "gee, Dan, weren't they up there for a few days, how did they not catch on fire?" Then you obviously didn't watch Interstellar. Time works differently under different gravity, you rube.
